What to do if the LED is flashing red every 1 second on my Hoymiles DTU-W100 Measuring Instruments?

If the LED on your Hoymiles Measuring Instruments is flashing red every 1 second, it indicates that the DTU has no ID and is disconnected from Wi-Fi. To resolve this, first, verify the distance between your router and the DTU, ensuring it's within the specified range. Next, double-check that you've correctly entered your home router's password during setup. Try connecting another device to your home router to confirm a stable and effective reception. As a further step, attempt connecting the DTU to a mobile hotspot to check if data uploading is successful.
